Is it possible to move a save state to the memory card?

[JosJuice]

It's not possible to simply move data from a savestate to a memory card, because the two use completely different formats. Only the game knows how to convert between those formats, so if the game doesn't let you save to the memory card, there isn't really anything you can do. If you want to avoid this in the future, make backups of your memory card often.
